Abstract

PURPOSE:To efficiently work a handy copying device by forming two adjacent working surface with a relative angle and providing a reader on one working surface and a reader on the other working surface. CONSTITUTION:When the picture and character and the like of an original are read, a working surface 2 travels with pressing the original through travelling rollers 8 and 10, the picture and the character and the like are read while synchronizing with an encoder 15 by a contact image sensor 5, an input signal is binarized and stored in a storage. On the other hand, when a handy copying device 1 writes on an arbitrary external position, travels a working surface 3 with pressing another paper through the travelling rollers 9 and 10, fetches a storage content while synchronizing with the encoder by a thermal head 6 and writes the character, etc. Since the writing and reading devices have the relative angle and comprise the adjacent working surface, no contact is made with the writing device at the time of the reading and the stain of the original caused by a contact with an ink ribbon and the reduction of the durability of the head can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a handy copying device that can be easily held with one hand and can read images, characters, etc. of a document and copy them.

[Conventional technology]

One example of conventional handy copy devices is one in which a reading device is provided on the operating surface, and images, characters, etc. of a document read by the reading device are copied onto a built-in paper and can be taken out. In addition, a writing means is provided on the operating surface, and an image is stored in advance in a built-in storage means.
Is there something that allows you to write characters etc. anywhere on the outside?

However, there is no handy copy device that has both of the above two types of functions. This is because if the reading means and writing means are provided on the same operating surface, the following problems will occur. That is, even during reading, the writing means comes into contact with the document surface, which places an unnecessary burden on the head of the writing means and reduces its durability.
Alternatively, the ink ribbon of the writing means may come into contact with the document and stain it. For this reason, there are problems in that a mechanism for retracting the head and the ink ribbon inside is required during reading, and a mechanism for stopping the feeding movement of the ink ribbon is required.

〔the purpose〕

Therefore, in the present invention, the shape of the writing means is devised so that it does not come into contact with the document surface during reading, thereby placing a burden on the head and reducing its durability, or preventing the ink ribbon from contacting the document and smudging it. An object of the present invention is to provide a handy copy device having both a reading function and a writing function, which can prevent such problems.

[Means for solving problems]

The handy copy device according to the present invention has two operating surfaces adjacent to each other at a relative angle, and one of these operating surfaces is provided with a reading means, and the other operating surface is provided with a writing means.

〔Example〕

Embodiments of the present invention will be described below based on the drawings. Figures 1 and 2 show the first part of the handy copying device according to the present invention.
It is a figure showing an example.

In the handy copying device shown in FIG. 1, two operating surfaces 2 and 3 are formed at the tip thereof. The working surfaces 2 and 3 are formed adjacent to each other at a relative angle θ, and the working surface 2 is provided with a contact image sensor 5 (reading means), and the working surface 3 is provided with a thermal head 6 (writing means). It is being Running rollers 8 and 9 are provided at one end of each of the operating surfaces 2 and 3, and a common running roller 10 is provided at the other end of each of the operating surfaces 2 and 3 adjacent to each other.

The traveling rollers 10 are capable of transmitting their rotation to an encoder 15 via a gear train rotation transmitting means 12 comprised of gears. The running roller 9 is configured to be able to transmit its rotation to a ribbon winding gear 16 that drives an ink ribbon (not shown) of the thermal head 6 via a gear train rotation transmission means 13 which is also constituted by gears.

As shown in FIG. 2, the encoder 15 is composed of a slit disk 20 pivotally supported by a shaft 18, and a photocoupler 21 that sandwiches the circumferential portion of the slit disk 20 from both the front and back sides and detects whether light passes or is blocked. has been done.

When reading two characters or the like in an image of a document (not shown), such a handy copy device 1 moves the operating surface 2 by pressing it onto the document via the running rollers 8 and 10, and the contact image sensor 5 reads the image. While synchronizing with the encoder 15, the nine characters in the image are read, and the input signal is binarized and stored in a storage means (not shown). The synchronization by the encoder 15 is such that the rotation of the traveling roller 10 when the contact image sensor 5 on the operating surface 2 travels on the document is transmitted to the slit disk 20 of the encoder 15 via the gear train rotation transmission means 12.
As a result, the light from the photocoupler 21 passes through or is blocked by the slit 20a of the slit disk 20. For example, when the light from the photocoupler 21 moves by one threshold, the slit 20a changes to 8.
This is done by inputting pulses generated by repeating the passing and blocking of the beam into a storage means (not shown).

When the handy copy device 1 writes on any external location, for example, on another paper surface such as a report or a paper, or on a flat surface other than paper, the operating surface 3 is transferred to another paper surface etc. via the running rollers 9 and 10. The device is pressed against the device and run, and while synchronized with the encoder 15 by the thermal head 6, the stored contents are retrieved from the storage means and one character or the like of the image is written. For writing by the thermal head 6, the ribbon winding gear 16 is rotated by the running roller 9 via the gear train rotation transmission means 13, and the ink ribbon comes into contact with the tip of the thermal head 6 due to the rotation of the ribbon winding gear 16. This is done by thermally changing the fine pixel portions of the thermal head 6 while moving. Switching between the reading mode and the writing mode can be performed using a manual changeover switch (not shown).
