Description

TECHNICAL FIELD The present invention relates to a recording apparatus for recording using transfer paper.

[Prior Art and its Problems] In a recording apparatus using a transfer paper, the transfer paper needs to be exchanged as necessary because the ink of the transfer paper is consumed during transfer recording.

Further, since the recording paper is also consumed, it must be replenished at an appropriate time.

In order to smoothly perform such transfer paper exchange and recording paper replenishment, a transfer paper cartridge has been proposed in which a transfer paper storage unit for storing transfer paper and a recording paper storage unit for storing recording paper are integrated. There is.

That is, when replenishing recording paper or exchanging transfer paper, check the other consumption condition, and if the consumption is considerably advanced, prepare this in advance so that these operations can be performed smoothly. This makes it possible to avoid an unforeseen situation such as having no transfer paper at hand.

However, the transfer paper cartridge in which the transfer paper storage unit and the recording paper storage unit are integrated is as large as that.
Therefore, when the transfer paper is exchanged and the recording paper is replenished, the transfer paper cartridge requires a large amount of force to be attached to and detached from the recording apparatus main body, and the workability is reduced accordingly.

Further, since the transfer paper has to be arranged between the thermal head and the platen roller, the transfer paper cartridges that have been proposed so far in order to satisfy such requirements are large, and therefore, the recording devices of the past have been used. The main body has the drawback that it is necessarily large.

[Means for Solving the Problems] The present invention has been made in view of the above problems, and uses a transfer paper cartridge that stores transfer paper wound between a supply-side roll and a winding-side roll. A recording apparatus for recording transfer paper by arranging it between a platen roller and a thermal head, which holds the supply-side roll or the take-up-side roll when the transfer paper cartridge is mounted and transfers the transfer paper cartridge. A recording apparatus having a transfer paper pulling-out unit that pulls out to the outside to transfer and set the transfer paper to a predetermined position of the apparatus, and the transfer paper pulling-out unit rotates coaxially with a rotation axis of a platen roller as a rotation fulcrum. The present invention provides a recording device that uses a rotating member.

By the operation of, the groove 5 of the transfer paper storage portion 2 is set at a predetermined position through the process shown in FIG. The operation of pulling out the transfer paper from the cartridge and setting it at a predetermined position is called transfer paper loading.

That is, as the lever 16 rotates, that is, when the projection 23 provided on the lever 16 reaches the position for activating the detecting means 24, the motor 19 stops its operation, and the lever 16 therefore stops its position (see FIG. 2). And the take-up roll 8 held by the lever 16 is provided with a gear 28, and the gear 28 meshes with the gear 27 so that a predetermined position is reached. Will be set to.

During operation of this lever 16, the thermal head
26 is retracted to the position shown by the alternate long and short dash line in FIG. 3, and the transfer paper 6 between the supply side roll 7 and the winding side roll 8 is located between the platen roller 11 and the thermal head 26. After the lever 16 is stopped, the thermal head 26 approaches the position indicated by the two-dot chain line in FIG. It is ready to start. That is, thereafter, a recording sheet (not shown) is fed from the bottom side of the recording sheet storage section 3 onto the platen roller 11 by a predetermined means (not shown), and the thermal head
26 is a platen roller with the recording paper and transfer paper 6 sandwiched between them.
It is pressure-bonded to 11, and a predetermined signal current is sent to the thermal head 26 to heat the thermal head 26, the ink of the transfer paper 6 is transferred to the recording paper, and printing is performed.

Further, when the transfer paper 6 has been wound up on the winding side roll 8 and is to be replaced with a new transfer paper 6, the unloading switch (not shown) is turned on, or the transfer paper ends. When it is detected, the operation reverses to the above case, that is, the motor 19 rotates in the opposite direction, and the lever 16 moves clockwise in FIG. 2 (counterclockwise in FIG. 3). The take-up roll 8 that has rotated and is held by the U-shaped notch 17 at the tip of the lever 16 is at the position indicated by the solid line in FIGS. 2 and 3, that is, the transfer paper cartridge 1
