JPH01262975A - Automatic cleaning device for sensor - Google Patents

Abstract

PURPOSE:To automatically clean a sensor, by causing an air spray to spray air automatically by means of electric signals from an information processor, a time supervisory timer, and a manual start switch. CONSTITUTION:An information processor 1 delivers an electric signal 2 every time it reads or with every printing sheet. A counting circuit 3 which counts the electric signal 2 to output a starting signal when the counting reaches a set point, a timer 4 which is capable of setting variable starting time intervals, and a manual start switch 5 are connected to a driving control unit 6. The driving control unit 6 determines pressing time and number of pressing of an air spray depending on predetermined conditions in response to a signal from any one of said three means to sand a driving signal to a driving unit 7, where, upon receiving the signal, an air spray press bar 8 is moved to press the valve of an air spray 10 to spray air, enabling thereby automatic cleaning at decreased maintenance cost.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic sensor cleaning device, and more particularly to an automatic sensor cleaning device that cleans a sensor in an information processing device by ejecting air spray.

[Conventional technology]

Punch-hole card reader, optical character reader.

Various sensors are used inside automatic deposit and savings transaction devices, dry toner printing devices, etc., and the cleaning work of the sensors inside the devices during maintenance of these information processing devices is
Conventionally, this was done by manually injecting air spray based on the results of equipment operation status management and patrol inspections.

[Problem to be solved by the invention]

The cleaning work for the sensors of the conventional information processing equipment described above is done manually by spraying air, and this has the disadvantage of increasing labor costs as maintenance personnel have to go around the equipment installation site and perform the cleaning work. There is.

In addition, it was necessary to constantly manage the status of the equipment, making it difficult to perform appropriate cleaning in response to sudden changes in operating status.

Therefore, depending on the operation status of the device, there is a drawback that an error in the device itself is detected only after the characteristics of the sensor change due to dust, and the operation of the device stops.

An object of the present invention is to provide an automatic sensor cleaning device that automatically cleans sensors in an information processing device without manual intervention.

[Means to solve the problem]

The automatic sensor cleaning device of the present invention includes an air spray that injects air to clean a sensor in an information processing device, a counting circuit that counts the number of processing times of the information processing device, a timer for setting time intervals, and a manual an operation switch; a drive control section that receives signals from any one of the counting circuit, the timer, and the switch and generates a drive signal for controlling the ejection operation of the air spray; It is configured to include a driving section for driving.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. The information processing device 1, that is, a device such as a perforated card reading device, an optical character reading device, an automatic deposit transaction device, a dry toner printing device, etc., sends out an electrical signal 2 for each number of sheets read or printed. A counting circuit 3 that counts this electrical signal 2 and outputs a starting signal when a set value is reached, a timer 4 whose starting time interval can be variably set, and a manual starting switch 5 are connected to the drive control section 6. Then, the drive control unit 6 determines the press time and number of times of the air spray according to the preset conditions based on the signal from one of the champions, and transmits the drive signal to the drive unit 7. In the drive section 7, the air spray push-up rod 8 is moved by this drive signal, and the valve of the air spray 10 in the air spray set section 9 is pressed down to blow out air. The ejected air is passed through the hose 11.
It is guided by a sensor 12 built into the information processing device 1, and its ejection force removes dust.

According to this configuration, the counting circuit 3. By appropriately setting the timer 4 according to the information processing device, cleaning can be automatically performed periodically and in accordance with the operating status of the device.

〔Effect of the invention〕

As explained above, the present invention automatically ejects air spray using an electric signal from an information processing device, a time monitoring timer, and a manual start switch to perform cleaning, thereby saving labor in maintenance work of the device. It becomes possible to clean according to the operation, which has the effect of preventing failures and reducing maintenance costs.
