Abstract

PURPOSE:To eliminate the restrictions on the thickness or size of a recording medium and enable recording on a booklet form recording medium, by detecting the movement of a main body of a recorder and recording in accordance with the movement. CONSTITUTION:When a main body A of a recorder is pressed against a booklet form recording paper such as a notebook so that an ink side of an ink ribbon is brought into the recording paper, a recording head 18 is pressed against the recording paper, with the ink ribbon therebetween. When the main body A is manually moved while pressing a recording start switch 21 in this condition, a rotatable member 7 making contact with the recording paper is rotated, and the rotating quantity and the rotating speed are detected by an encoding plate 10 and a photosensor 11. Namely, the moving quantity of the main body A is detected based on the number of pulses generated after the start of the movement, and the velocity of movement is detected based on the period of the pulses. Recording information stored in a RAM is read according to the results of the detection, and the recording head 18 is driven according to the information. Therefore, image recording corresponding to the velocity of the main body A is constantly carried out, under variations in the velocity.

(Paper, plastic sheets, etc., below 1 record)
5) and moving it manually or the like allows for predetermined recording.

Here, the configuration of each mechanism B, C, and D will be specifically explained based on FIG. 2.

First, to explain the detection mechanism B, the axis G of the lower case 2
aL This rotating member 7 is rotatably attached, and the member 7
is designed to rotate as it moves to the main body of the device. That is, the rotating member 7 has a roller portion 7a and a 1lo-ra portion 7.
A gear portion 7b having a smaller diameter than the gear portion a is integrally formed, and the roller portion 7a is attached so that the notch of the lower case 2 protrudes outside from the portion 2a. Therefore, when the roller portion 7a is brought into contact with the recording paper 5 and moved toward the main body of the apparatus, the rotating member 7 rotates in accordance with the amount of movement and the speed of movement. This rotation is caused by the intermediate gear 8 meshing with the gear portion 7b.
and the Entsu 1 via the intermediate gear 9 that meshes with the gear 8.
'Gear portion of plate 10] Oa. The gears 8 and 9 and the encoder plate 10 are the shafts 6b and 6c of the lower case 2, respectively.

It is rotatably attached to 6d.

The above encoding board■0 is i? The gear part 10a and a thin disc IOb made of stainless steel or the like are integrally formed, and the disc 1
A plurality of rectangular slits Oc are provided radially around 0b. A photosensor 11 is provided at the position of the slit IOc. This photo sensor 1
1 has a light-emitting part and a light-receiving part, and the lower case 2 is arranged so that the light from the light-emitting part passes through the yXOc and reaches the light-receiving part.
The sensor is attached to the portion 11a. Therefore, when the rotating member 7 rotates, the encode plate 10 rotates correspondingly, and the photosensor If detecting the slit IOc emits a pulse signal. Based on this signal, the rotation amount and rotation speed of the rotating member 7 are detected.

Note that guide rollers 30a and 30b for guiding the movement of the main body A are rotatably attached to both sides of the main body A of the apparatus.

Next, the transfer medium transport mechanism C will be described. A rectangular rotor 12 is rotatably mounted on the shaft 6c of the lower case 2, and the rotor 12 is connected to a gear 131 that meshes with the intermediate gear 8. Disc 14. They are press-fitted into the winding shaft 16 with the compression coil spring 15 sandwiched therebetween.

Further, the gear 13 is rotatably attached to the rotor 12, and the disc 14 is loosely fitted to the rotor 12 so as not to rotate. Further, a friction plate 13a made of felt or the like is fixed to the upper surface of the gear 13 with adhesive or the like.
The disc 14 is pressed against this friction plate 13a by the bias of a coil spring 15, thereby forming a friction clutch.

The winding shaft 16 is connected to an opening 1 formed in the upper case 1.
The upper case 1 is configured to be exposed from the upper case 1, and a supporting shaft IC is provided protruding from the upper case 1. When the ink ribbon cassette 4 is loaded into the upper case 1, the feed-out rule 4a of the cassette 4 is rotatably supported by the support shaft 1c, and the take-up rule 4b is rotated relative to the take-up shaft 16. The two are configured to be non-rotatably fitted.

An ink ribbon 17, which is a transfer medium, is wound around the feed reel 4a and the take-up reel 4b, and when the take-up reel 4b rotates, the ink ribbon 17 is sequentially fed out from the feed reel 4a to the take-up reel 4b.

The ink ribbon 17 is formed by coating a base film made of polyethylene terephthalate film or the like with ink that melts or becomes less viscous when heated, and is pressed from the base film side by a recording head 18 (described later) to coat the ink. It is loaded so that its surface can come into contact with the recording paper 5.

In the above configuration, when the rotating member 7 rotates, the intermediate gear 8
The gear 13 rotates through the
is transmitted to the disk 14 through the frictional force of the winding shaft 16.
rotates. This causes the take-up reel 4b to rotate,
The ink ribbon 17 is sequentially wound onto a take-up reel 4b.

Note that when the ink ribbon 17 is wound up, rotational force exceeding a certain level is not transmitted to the winding shaft 16 due to the action of the friction clutch described above.

Next, to explain the recording head mechanism, 18 is a recording head, and a plurality of heating elements 18b that individually generate heat when energized are arranged in a row on a head substrate 18a, and the recording head 18 is bonded to a head support member 19. It is fixed by etc. This head support member 19 is rotatably attached to a shaft 6f of the lower case 2, and a shaft 19a protruding from an arm portion of the member 19 and both arm portions of a torsion coil spring 20 are attached to the shaft 6g of the lower case 2. It is locked. Therefore, the recording head 18 is urged by the torsion coil spring 20 so as to receive a moment in the clockwise direction in FIG. ing.

The recording head 18, photosensor 11, and recording start switch 21 are electrically connected to a circuit board 23 via a flexible substrate 22 or the like. This circuit board 2
3 is provided with a control circuit to be described later, and the control circuit controls the driving of the recording head for one day.

The above control circuit is constructed as shown in FIG. In addition, in the figure, the part surrounded by the two-dot chain line is the circuit board 2.
3, and the part E surrounded by the dashed line
is a circuit provided in an external device such as a word processor.

To explain the above circuit, the power supply 24 is the CPU 25,
RAM26. Photo sensor 11. Recording head 18
supplied to Recorded information input from the keyboard 27 is stored in the RAM 26 via the CPU 25. When the recording start switch 21 is pressed and the rotating member 7 rotates, pulse signals are sequentially input to the CPU 25 from the photosensor 11 that detects the slit 10C of the disk 10b.

This CPU 25 reads recorded information previously stored in the RAM 26 in response to a signal from the photosensor 11, and drives a driver 2 for driving the recording head.
8, the heating element 18b of the recording head 18 generates heat in an image pattern, thereby transferring and recording the ink on the ink ribbon 17 onto the recording paper 5.

After recording, the ink ribbon 17 is configured to be wound onto the take-up reel 4b by transmitting the rotational force of the rotating member 7 to the take-up shaft 16 via the friction clutch 29.

Next, a case will be described in which the recording apparatus configured as described above is used.

As shown in FIG. 4, a cord 33 electrically connects an external device 31, such as a word processor or an electronic typewriter, for inputting recorded information to the control circuit of the main body A of the apparatus.

For example, when inputting information using the keyboard 27 of the external device 31 and recording input information displayed on the display section 32, the device is configured such that the ink surface of the ink ribbon 17 contacts the booklet-like recording paper 5 such as a notebook. When the main body A is pressed, the recording head 18 presses the ink ribbon 17 against the recording paper 5.

In this state, when the main body A of the apparatus is manually moved while pressing the recording start switch 21, the rotating member 7 in contact with the recording paper 5 rotates, and the amount and speed of rotation are detected by the encode plate 10 and the photo sensor 11. Ru.

That is, the amount of movement of the apparatus main body A is detected based on the number of pulses from the start of movement, and the moving speed is detected based on the pulse period. Recording information stored in the RAM 26 is read in response to this detection result, and the recording head 18 is driven in accordance with the information. Therefore, even if the moving speed of the device body A changes,
Image recording is always performed in accordance with the speed.

Further, the rotation of the rotating member 7 accompanying the movement of the apparatus main body A rotates the take-up shaft 16, and the ink ribbon 17 after recording is sequentially wound onto the take-up reel 4b.

Note that as the ink ribbon 17 is wound up, the diameter of the ink ribbon 17 wound around the take-up reel 4b changes. Therefore, the amount of movement of the take-up reel 4 relative to the amount of movement of the device body A
Although it is necessary to change the rotation amount of b, a rotation torque corresponding to the rotation amount of the rotating member 7 is transmitted to the winding shaft 16 via the friction clutch 29 as described above. Therefore, the ink ribbon 17 is wound onto the take-up reel 4b by an amount corresponding to the amount of rotation of the rotating member 7, regardless of the change in the diameter.

Since recording can be performed by moving the main body A of the apparatus as described above, the recording medium is not limited to a sheet-like one, and it is possible to easily record on a thick one or a booklet-like one. Further, since the drive of the recording head 18 and the rotation of the take-up shaft 16 operate in synchronization with the rotation of the rotating member 7, the ink ribbon 17 is not conveyed and only the recording head 18 is driven. The ink ribbon 17 is never transported without the recording head 18 being driven.

Incidentally, in the above-mentioned embodiment, an example was shown in which the movement amount of the apparatus body A was detected and the ink ribbon 17 was conveyed by rotation of the rotating member 7, but the detection and conveyance may be performed in independent configurations. You may also do this using

Further, the rotating member 17 is not limited to a roller-like member, and may be a rotating member such as an endless heald, for example.

Further, in the above embodiment, the rotation of the rotating member 7 is detected by the combination of the encoder plate 10 and the photosensor 11, but the present invention is not limited to this, and other methods such as Instead of the encode plate 10, a magnetic pole plate in which N and S magnetic poles are arranged alternately is attached to rotate corresponding to the rotating member 7, and by detecting the rotation of the magnetic pole plate, the amount of rotation of the rotating member 7 is detected. In the above-mentioned embodiment, an example of a thermal transfer type was shown in which the ink ribbon 17 coated with heat-melting or low-viscosity ink is used as the transfer medium, and recording is performed with the thermal recording head 18. Other wire dot recording methods can also be applied in the same way.

Further, in the above-mentioned embodiment, an example was shown in which the external device 31 was provided separately and recorded information from the external device 31 was recorded, but the external device 31 was also integrated as the other side, and the control shown in FIG. The entire mechanism may be housed in the device body A so that the recording device can be used alone, or the recording device described above may be attached to an external device 31 such as a word processor so that it can also be used as a recording device for the external device 31. It's okay.

<Effects of the Invention> As described above, the present invention detects the movement of the device main body and records according to this movement, so that it is not possible to manually record on a booklet-like recording medium such as cardboard or a notebook. I can do it.

Furthermore, if the movement of the apparatus main body is detected by a rotating member, and the transfer medium is further conveyed by the rotating member,
The movement of the apparatus main body, the drive of the recording head, and the conveyance of the transfer medium can always be synchronized, and as a result, it is possible to eliminate transfer defects and waste of the transfer medium.
