Also disclosed is a preferred embodiment in which a channel indicator is remotely mounted so as to be readily visible, the indicator being positively and synchronously connected with both the selector switch and the print head.，下面是Multi channel monitoring and printing recorder apparatus专利的具体信息内容。

权利要求

1. In a multi point recorder including a plurality of input terminals; a selector switch means for monitoring respective said input terminals; indexing means for simultaneously and synchronously moving said selector switch means and indexing a print head; measuring means for measuring the input signal present on the input terminal selected by said selector switch; positioning means connected with said measuring means and with said print head for positioning said print head at a position corresponding to the magnitude of said input signal; the improvement comprising: a. a plurality of bypass switch means for signalling whether respective input terminals are to be monitored or bypassed; b. a bypass deck means having a plurality of contacts connected with respective said bypass switch means, an output terminal, and interconnection means for connecting said output terminal with respective ones of said contacts; said interconnection means being connected with said selector switch means so as to track synchronously therewith and connect said contacts with said output terminal in synchronism with said selector switch means connecting a corresponding input terminal; c. a scan timer means for generating periodic signals, each periodic signal initiating a print operation; d. print signal generator means connected with said scan timer means for generating in response to respective said periodic signals a desensitize signal; a print signal; and, after a timed interval, a set-reset signal; e. desensitizer means connected with said print signal generator means and said positioning means for desensitizing and stopping said positioning means in response to a desensitize signal; f. print means connected with said print signal generating means and operable to effect printing via said print head in response to said print signal; g. index signal generator means connected with said print signal generator means, with said desensitizer means, and with saId indexing means for generating in response to said set-reset signal a continuing desensitize signal and an indexing signal; for transmitting said continuing desensitize signal to said desensitizer means; and for transmitting said indexing signal to said indexing means; said indexing signal effecting indexing of said selector switch and said bypass deck means to the next input terminal that is not to be bypassed; said indexing signal generator means also being connected with the output terminal of said bypass deck means for stopping said indexing and terminating said continuing desensitize signal in response to being connected with a properly positioned bypass switch.

2. The multi point recorder of claim 1 wherein said desensitizer means is also connected with said scan timer means so as to inhibit the beginning of the timing period as long as a desensitize signal is being sent to said desensitizer means.

3. The multi point recorder of claim 1 wherein said print signal generator means contains a reset means that is connected to receive said set-reset signal for preventing generation of another print signal until reset by said set-reset signal.

4. The multi point recorder of claim 1 wherein said desensitizer means contains a desensitizing timer means for continuing the desensitizing and the stopping of said positioning means for a predetermined interval of time after discontinuance of a desensitize signal.

5. The multi point recorder of claim 1 wherein said index signal generator means contains a reset means that is connected internally to receive a reset signal and said index signal generator means contains a timer means for generating said reset signal after the expiration of the predetermined time from the time said interconnection means of said bypass deck means is indexed from the contact corresponding to the channel just printed, whereby acceptance of and response to another set-reset signal is prevented before receiving said reset signal.

6. The multi point recorder of claim 1 wherein said interconnection means comprises a mechanically operable wiper arm that is physically connected with said selector switch to move synchronously therewith.

7. The multi point recorder of claim 1 wherein said plurality of bypass switches are electrical switches that are electrically connected with respective contacts on said bypass deck means, said bypass switches being contained in a separable unit that may be employed remote from the recorder.
