A method to count tickets which includes a translucent ticket with an opaque pattern with translucent portions, including a light source on the first side of the ticket and a detector on a second side of the ticket, providing relative motion between the ticket and the detector. The expanding card mechanism includes an upper case, a lower case, a plastic frame rack, a plastic baffle and an interface joint. Other embodiments are described and claimed. The top of the connector contacts a first surface of the printed board, and each columnar convexity is fixed to the printed board via the corresponding protrusion with a first screw. A control buffer file for the added control data and a document buffer file for the document data are automatically formed and stored by a control device program running on the processing computer. The variable bit rate is determined based on a source feature of the speech signal and the reserved bits is obtained based on the target bit rate.
