Abstract

PURPOSE:To prevent an image from sticking out of an area by setting an image recording area and performing variable power accordance with the area. CONSTITUTION:The counting time T of a timer 30 for setting a recording position is inputted by a setting part 20 such as a numerical value inputting key, etc. When a copying starting signal S comes, a CPU 3 performs the count-up of the timer 30 till the time T comes in accordance with the clock (t) in a clock generating device 50 and the CPU 3 starts to read dating data from an RTC 6. The CPU 3 forms the letter font data for driving an LED head 2 for writing on a RAM 5 based on the above data. The head 2 is driven in synchronism with the driving clock (t) in a motor driving circuit 40 of a drum 7 based on the above-mentioned data and the dating data is transferred on the drum 7. Then, the position on the recording paper is changed from (b) to (c) with the time T. Thus, it can be prevented that the image sticks out of the area.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording device that records images such as characters and marks in a predetermined area.

[Prior Art] Conventionally, reader printers that imprint hard copies of microfilm with other text information marks, etc.
It is configured as shown in FIG. 0, and the original image on the microfilm F is enlarged by a lens 101. And the image is
Mirror 102.1 via moving mirror 102.103
The image is projected onto the drum 7, which is rotating in synchronization with the moving speed of 03, to form an image. On the other hand, the additional information imprinting device 2 built into the main body uses a light bulb or light emitting diode (LE).
By blinking D) in accordance with the character information to be recorded,
A character information image is additionally formed on the drum 7 through the lens 104.

On the other hand, sheets are selectively fed from the cassette Kl, 2 containing the copy sheets at a speed synchronized with the rotational speed of the drum 7 by paper feed rollers 10Sa, 105b. Since the image on the drum is visualized by a developing toner in a developing device (not shown), the toner image is transferred to the paper on the transfer charger 106, passes through the conveyance path 107, and is transferred to the fixing device 10.
8, and is fixed on the paper ejection tray 1 by the paper ejection roller 109.
The paper is ejected to 10. In this order, the image on the film and the text information are printed on the same paper.

Problems that invention is trying to solve] However,
In the above conventional example, since the recording position of the character information on the recording paper is fixed, it overlaps with the image of the image information on the film as shown in Figure 11, making it difficult to distinguish, and as shown in Figure 12. When the number of recorded characters becomes large, as in the case of , the disadvantage is that the length of the recording paper cannot be filled.

[Means for Solving the Problems] The present invention provides an image outputting means for outputting an image, an area setting means for setting a recording area in which the image is recorded, and a scaling of the image according to the recording area. The present invention provides an image recording apparatus that can set an area for recording one image by providing a variable magnification means and a determining means for determining whether the variable magnification ratio of the variable magnification means is equal to or less than a predetermined value m.

[First example] The present invention will be explained below according to examples.

FIG. 1 is a schematic diagram of an exposure apparatus unit. 1 is a control unit of the exposure equipment unit, 2 is a 7-dot LED array head as a writing light source, 3 is a CPU, 4 is a read-only memory (ROM), 5 is a random access memory (RAM),
6 is a real-time clock (RTC), 7 is a transfer drum of the printer, and S is an external copy start signal.0 In this embodiment, the date is recorded as write information.

Next, an outline of the operation of this embodiment will be explained based on the flowchart of FIG. 2.

First, the user inputs the count time T of the recording position setting timer 30 using the numerical manual key setting section 20 (step 521). (step 522)
When the copy start signal is received, the CPU 3 increments the timer 30 in accordance with the clock t generated by the clock generator 50 until the time T is reached (steps S23 and 24).

The CPU 3 reads date data from the RTC 6 (step 525).

Next, the CPU 3 creates 5×7 dot character font data for driving LED head 2 on the RAM 5 according to the above data (step 526).
The head 2 is driven by the CPU 3 in synchronization with the drive clock t of the motor drive circuit 40 which rotates the drum 7 according to the character font data, and date data of 5×7 dots is transferred onto the drum (step 527).

Therefore, the position on the recording paper can be changed as shown in FIGS. 3(b) to 3(c) depending on the time T set on the timer.

[Second example] A configuration diagram of the second embodiment is shown in FIG.

60 is a frequency converter. Components common to those in FIG. 1 are given the same numbers, and explanations thereof will be omitted.

This embodiment is an embodiment in which the character width is reduced according to the space in which the characters are recorded.

l! of the operation of the second embodiment! E will be explained with reference to the flowchart in FIG. Descriptions of the same items as in the previous embodiment will be omitted.

When the user inputs the count time T using the setting section 20 in step S21, the character is determined from the length of the paper in the character information recording direction and the paper conveyance speed (rotational peripheral speed of the developing drum), as shown in FIG. The length of the information writeable range or the following is calculated (step 531).

Assuming that the number of dots in the recording direction of character information is 5 dots per character, the number of character information characters is N, and in order to record all the character information within the long writeable range, the LED
1 The maximum lighting time t of a dot is.

or can be calculated (step 532).

Therefore, the CPU 3 uses a clock generator 50 as shown in FIG.
The lighting time t2 of one LED dot for forming a standard character length in which 1+ is generated is compared with 1+, and one lighting time t is set as shown in FIG. 7 (step 533).

That is, 12>1. In this case, the standard character length will cause the character information to protrude outside the writable range, so
1. As a driving clock for ED2. (Step 5)
34). That is, character information is recorded with variable magnification.

Then, the CPU 3 controls the frequency converter 60 and converts the clock t2 generated by the clock generator 50 into the clock 1. Convert it to .

On the other hand, when t2≦t, the standard character length is within the writable 1# range, so t2 is used as the driving clock for LED2 (step 535). is never done.

Then, when the copy start signal S is received from the sensor 10, the CPU 3 activates the recording position setting timer 30 based on the clock t2.
After waiting in accordance with the time, character font data is created in accordance with the date data of the RTC 6, and the LED head is driven and illuminated according to the character font data at clock t (steps S22 to S27).

That is, the CPU 3 drives the motor drive circuit 40 with the clock t2 generated by the clock generator t2. Also, timer 3 determines the character recording start position.
0 (count time T) is counted up at clock t2. The driving clock for the LED head, which determines the length of the character, is the clock 1 generated by the frequency converter 60.
or t2 generated by the clock generator t2 is selected and used.

Therefore, as shown in FIG. 8, character information is recorded with a length corresponding to the character information recording range.

Furthermore, in this embodiment, in step S34, the CPU 3
is clock 1. is compared with a predetermined value. If the value is less than a predetermined value, that is, if it is determined that the length of the characters in the recording direction after scaling has become shorter than a certain value and the characters are difficult to visually recognize, the display 7o is turned on and the user issue a warning. Then, the process returns to step S21 and waits without performing the operations from step 322 onwards. Thereafter, the user changes the count time T using the setting section 20. Then, characters can be stored in the appropriate position δ.

Furthermore, in this embodiment, the operator can also set the length of one character using means such as an input key.

Furthermore, in this embodiment, if multiple lengths of recording sheets are considered, one cassette containing sheets of a certain shape as shown in FIG. 1θ is used. If a means (sensor, microswitch, etc.) is provided to determine 2 based on the paper size, L can be determined correctly even if the paper size is different, and there is no problem. Even if it is defined as an area in which character information can be recorded that is shorter than the length of the shortest recording paper available, the character information will not be missing (see FIG. 9).

[Other Embodiments] In the above embodiments, the date is recorded as additional information.If it is useful information to be added at the time of copying, it is not limited to characters such as 1 date, but a mark or the like may be used. Alternatively, automatic or manual selection means may be provided so that a plurality of pieces of information can be selectively recorded.

In addition, although a 7-dot LED array was used as the writing head, the shape of the dots or the number of dots is not limited to those in the example, and if the light intensity and speed are sufficient, a liquid crystal shutter can be used. A structure combining lamps, writing using a semiconductor laser, etc. are conceivable.

Further, the transfer medium is not limited to the drum for a copying machine, and of course, other media such as IR salt film may be used.

Further, the timer used in the embodiments may be realized by a software method or by a hardware method such as a dedicated IC.

[Effects of the Invention] According to the present invention, an image can be recorded at an appropriate position by setting an area for recording an image. Furthermore, since the magnification is changed according to the recording area, it is possible to prevent two images from protruding from the area. Furthermore, since it is determined whether or not the magnification ratio becomes less than a predetermined value and it becomes difficult to visually recognize the image, the user can take appropriate measures according to the situation.
