Abstract: An electronic musical system in which tone generator parameters of each of tone generators respectively assigned to tracks of a sequencer of an electronic musical apparatus can easily be controlled by using a musical control apparatus, while tracks are switched. In the setting of the tone generator parameters of the tone generators assigned to the tracks, setting contents are input by using control operating elements of the musical control apparatus. There are prepared in advance templates in each of which control operating elements are made to correspond to tone generator parameters controlled by the control operating elements, and each tone generator is made in one-to-one correspondence with one of the templates, whereby tone generator parameters of a tone generator assigned to a track currently designated by a user are set by manipulating the control operating elements of the musical control apparatus.

Abstract: In the case where an automatic reading file composed of plural kinds of detailed parameters stored in a transportable storage device whose attachment is detected has been already read in an apparatus, it is determined whether update, to a currently-read automatic reading file, of an automatic reading file stored in a storage section is carried out or not in accordance with a user's instruction, and is controlled so as to carry out a process. Namely, in the case where an automatic reading file has not been read yet, the automatic reading file stored in the storage section is updated to the currently-read automatic reading file without any condition. On the other hand, if an automatic reading file has been already read, the automatic reading file stored in the storage section may be edited on the basis of it.

Abstract: An image forming apparatus includes a cover frame that holds a held shaft of an optical writing unit to allow a free movement thereof and urges the optical writing unit in a predetermined direction by using an urging coil spring to bring the held portion shaft of the optical writing unit separated from the writing operation position into contact with a contact target portion thereof.

Abstract: In an image forming apparatus, a photoreceptor carries a latent image on its looped surface. An optical writing unit moves between an operating position at which writing of a latent image is performed on the looped surface of the photoreceptor and a standby position at which writing is not performed. A developing device develops the latent image carried on the photoreceptor. A reference position member is located at a reference position for positioning the optical writing unit. A positioning member positions the optical writing unit. A bias coil spring biases the reference position member so that the reference position member contacts the positioning member.
