Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a copying machine, and particularly to a personal copying machine suitable for specifying a copy width.

[Conventional technology]

Up until now, most of the plain paper copying machines on the market have been for office use, and for individuals, there have been 1 to 1 so-called manual copying machines that copy part of the original using thermal paper. There are only two types of small desk copying machines for personal or home use.

[Problem that the invention seeks to solve]

The challenges for the practical application of personal desktop copiers are to reduce the price and size, but when it comes to arbitrary specification of copy width, there is a limit to miniaturization with the general switch mechanism used in conventional office machines. Moreover, if a memory such as a microcomputer is used, the control circuit becomes complicated and costs are increased, and there is a problem in that it is only possible to copy paper of a certain limited size.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a personal copying machine that has a simple configuration and allows arbitrary designation of the copying machine.

[Means for solving problems]

The above purpose is to hold a U-shaped piece made of an elastic material such as plastic on the edge of an opening for document insertion in a copying machine frame so that it can slide freely in the width direction of the document paper against the edge of the opening. A permanent magnet is fixed on the carriage, and is made to face the Hall IC provided on the carriage in a non-contact manner.By touching the above U-shaped piece and moving the position, the non-contact sensor switch can actuate the magnet as desired. Copies can be made using a designated copy machine.

In this embodiment, the copying width, that is, the moving direction of the carriage is referred to as the main scanning direction, and the paper feeding direction is referred to as the sub-scanning direction. By pressing the copy switch 7, the copy switch 7 is pressed. Also, the oscillation circuit O
The clock generated by 8C is frequency-divided by the read timing generation circuit TM, and becomes a driving clock for the image sensor 16, a recording head driving clock, and a carriage feeding clock.

The image sensor driver DRVI amplifies the drive clock and supplies it to the image sensor 16. This read output is amplified by the amplifier AMP via the buffer BUFF. This output is sent to the concentration setting circuit C0 by the comparator CMP.
It is compared with the value of NT, becomes a binary signal, and becomes a latch LATC.
The data is taken into H and becomes data to be recorded by the recording head 59.

The record creation timing circuit WTM energizes the recording head 59 using the energization time setting circuit WT so as to record the data read by the recording head 59 in synchronization with the reading timing. The recording head 59 receives a predetermined number of pulses from the driver B using the head up/down counter HCNT.
: Drive the remoter 67 by DRVB and set it on the recording paper.

The main scanning counter MCNT drives the motor 57 by the driver A: DRVA to move the carriage 12 until the main scanning is completed by the main scanning sensor MLS which determines a preset counter number or main scanning length. After the main scanning is completed, the paper feed counter PCNT causes the driver C: DRVC to move the motor 33 by a predetermined length.
and motor 50 feeds the original and recording paper. After paper feeding is completed, the moving direction switching circuit DIR switches the main scanning direction. This causes the motor 57 to switch main scanning to the opposite direction.

Such main scanning and paper feeding sub-scanning are repeated alternately, and the copying operation is completed when a predetermined length is reached by the size switch 8 and the reading length setting circuit LS.

The basic operation of the personal copying machine according to the present invention configured as described above is to insert the document 1o and move the roller 21 to the arrow R2.
When the sub-roller 40 is turned in the direction of the arrow R8, the sub-roller 40 is also driven in the direction of the arrow R8. As a result of this operation, the original 10 is fed in sheets and is manually fed in the direction of arrow R4 to the paper discharge lower 4 up to the reading start point of the original 10, after which the paper is automatically fed. In addition, the selection of the copy size of the original 10 in the main scanning direction is performed using the U-shaped piece 81.
Manually operate the scale to match the scale 85 (Fig. 2).

Next, to set the recording paper 11 in the recording section 3, insert the recording paper 11 in the direction of the arrow W1, turn the knob 51, and turn the roller 47 in the Wz force direction.
The inserted recording paper 11 is driven in the lW4 direction and is moved to the platen 7.
The paper is ejected in the W6 direction between the ink ribbon 69 and the ink ribbon 69, and is fed to an appropriate position while adjusting its posture correctly.

Next, the operation section 1 is operated. First, the rotary switch 8 for specifying the copy paper size in the sub-scanning direction and the density switch 9 for adjusting the copy density according to the original density are pressed, and then the power switch 6 and the copy switch 7 are pressed in that order. Copying work is carried out by the operation of section 4.

〔Effect of the invention〕

By implementing the present invention, it is possible to operate a non-contact sensor switch by simply moving the U-shaped piece,
A personal copying machine that can be made smaller, lower in price, and improved in reliability, has a simple structure, is durable, has excellent 2/2 ratio, and can arbitrarily set the copying width has been obtained.
