In that example, a reading head and a print head are mounted on the same carriage as follows. The reading head is mounted on the carriage so that it can rotate around a shaft erected on the carriage between a position close to facing the paper and a position not facing the paper. The print head rotates integrally with the reading head, and is mounted on the carriage so that when the reading head occupies a position not facing the paper, it occupies a position close to and facing the paper; A switching means is provided on the carriage for causing one of the heads to approach and face the paper.

Therefore, both heads rotate about their axes, and when the reading head occupies a position close to and facing the paper, the print head does not face the paper, and the print head occupies a position close to and opposed to the paper. When the reading head is occupied, the reading head is not close to the paper.

[Problems to be solved by the invention] However, in the conventional device configured as described above,
When the ribbon cassette is attached to the carriage, there is a possibility that the ribbon cassette may prevent both heads from moving to a position close to and facing the paper.

Therefore, each time the head moves between a position where it does not face the paper and a position where it closely faces the paper, the operator must remove the ribbon cassette, which is a problem in that it requires time and effort. Further, in this device, it is impossible for the reading head and the print head to face the paper in close proximity to each other at the same time.

[Object of the Invention] The present invention has been made in order to solve the above-mentioned conventional problems, and when the two heads move to a position where they face each other in close proximity to the paper, the ribbon cassette mounted on the carriage is moved. The purpose is to provide an input/output device with good operability that does not require removal. Furthermore, it is an object of the present invention to provide a high-performance input/output device in which both heads are close to the paper surface, and the reading head can read the printed characters immediately after the print head prints, and can detect printing errors. .

Means and operation for solving problem E] To achieve this object, a print head and a reading head are disposed adjacent to each other on a carriage with a platen, and at least one of the two heads is connected to the platen. Head selection means for bringing the head closer to the paper surface is provided so as to move integrally with the sharpening ridge. As a result, head selection can be easily performed without the ribbon cassette mounted on the carriage interfering with the selection of both heads.
